Ok i got some time behind these binos now to give some of my opinions ($0.15 worth).
I currently own and my base line is Swarovski slc 10x42 and Swarovski ATX with 65m (have the 85 but use the 65 for backpack archery) also just added the me1.7 magnifier.
For here in the east i only able to tree stand hunt whitetail in our very longgggg archery season. The SLCs 10x42 are really nice in low light and in quick one hand verification thru thick areas to double check. Clarity and FOV are quite amazing.
Out west i have been lucky to hunt elk over the past coupe of years all archery and have taken the slcs and the spotter with me. I took the 85m lense for the spotter the first year and guess what I found out I needed to drop some weight. Thus i went to a 65m head this year and a new panning ball head. Dropped like 2 lbs but. Paid the $$.
The binos of course work very well but i wanted to get just a bit more magnification and didn’t want to lose the clarity and FOV i have with the slc 10x42 and i wanted to keep them on y Chest for hand use as needed. I was looking heavily into the slc 15x56 and all i heard was that you need to put these on a tripod, but i found some good demo pairs and i was still very tempted. The other Swarovski option was the 12x50 els but $$ and still wondering about hand use was on my mind.
So I started to look at other possibilities. After a lot of research In came Maven b2 11x45 and the B4 12x56 via their demo program. I also read a bit the SigSauer Zulu 9 11x45 and it was stated that people thought they were made in Japan in the same place (or at least the optics and components were from there). So i found a screaming deal on a demo set of Zulu 9 11x45 and pulled the trigger on them ( I am talking saving $300 !!) knowing i could return.
I tried all of them at night and during the day with my Swarovskis (will do some more though). I quickly feel i ruled out the idea of the b4 12x56 only because of the hand held use, these suckers are big and heavy. They are very good optically and the magnification is good but they really need to be on a tripod. FYI the good thing with both Maven & Zulu 9 is they can use the simple vortex like tripod attachment (which i hand from the past) .
So kept going back and forth with the Zulu 9 and B2.....I cant tell a single thing that is optically different between these to. Clarity , brightness FOV , etc...if there is one my eyes dont see it. They both feel very good in your hands it give you a very different feel. The Zulu 9 (they look like straight out of Star Wars) have a rubbery feel to them (like the Swarovski) and have angular cuts on the barrels that you can lock your hands on. They also have thumb indents just like my SLCs. Very comfortable for me but they do seem to lock your hand into one position as these are defiantly grips areas (again somewhat similar in feeling to my slcs minus the angular part). The focus knob has rubbery feel as well this indents in it. High and low points like a star knob. My fingers definitely grabbed onto these little high points to turn. It spun very smoothly.
The B2 are completely round. Your hands can go anywhere and your hands very comfortably wrap the entire barrel. Naturally my hands gravitated to the ends of the barrel. It felt good grabbing the hole tube but it did feel slick. Was wondering with gloves on and if its cold if it would be to slick. Not rubbery feel on these. The focus wheel on this is round with metal perfs but consistent throughout, i you feel like you can spin and spin easily. Wheel turns very smoothly and consistently. The demos came with the kryptic pattern on it with some black and dark green accents...man did it look nice.
These are both great binos and other than the cosmetic differences i cant tell them apart. I am going to go with the Zulu 9 11x45 in this case because of the $300 saving i got on them and the rubbery feel. But i can say if cost wise it was the other way around i would chose the B2. Performance wise there is no loser here. The feel is completely a personal thing.
Ok so comparing these to my Swarovski slc 10x42. The SLCs i feel i can actually focus a hair more with , as in i can get a tad more detail on them. We are talking splitting hairs here. Will it be the difference in seeing and elk vs not ? I dont think so. I did notice the 10x42 have a slight more FOV (lists 330 vs 314(5) ) so its real close. It’s not much and you can barely tell. Something like a 12x or 15x you start to get to under 300 and close to 200 feet at 1000yards. I do feel the Zulu/B2 are brighter than my SLCs in the day and i think i see a bit more in low light. I also did notice the extra magnification , sight but it was there if you were looking for it.
I have to say that if one was to go with the Zulu 9 or Maven B2 11x45 over the Swarovski slc 10x42 you would not be losing much if anything. From my personal tests i would say the SLCs are lighter and “easier” in single hand held use, the Zulu9/B2 are nice with the extra magnification and a hair more brighter, the SLCs provide a hair more detail.
So i will be keeping the Zulu 9 11x45, got a great deal, still have an easy to use by hand , added a hair more power and brightness and the FOV and clarity is still real close to my Swarovski SLC.
Hope that help anyone looking The Sig Sauer Zulu 9 11x45 the Maven B2 11x45 are both great choices
